Did not show nearly enough time setting / feeling the gauge in the actual bore.----That is the key element in using these !!
Yes, that part I get. I’m working on learning the “feel” you’ve explained earlier. I know I’m not doing it correctly now, or I wouldn’t be getting absurd results.
But this guy
1— sets or locks the pistons in place at a diameter larger than the cylinder diameter, then
2– inserts the tool off-kilter to get it in; then
3– uses a sweeping motion to bring the tool through vertical, then slightly past vertical, to force the pistons in.
I have been
1– putting the tool in unlocked, then
2– trying to use “feel” (or additional devices, like that flaring tool gimmick) to center it up and square it.
3— Then when I think (and hope and pray!) I’ve got it positioned right, I lock it, and tilt it a little to clear the cylinder walls and take it out.
It seems like his method will more likely get the pistons to self-center across the cylinder and thereby prevent under-measurements like I’ve been getting.
It’s worth a shot, I think.
I’ll still have to “educate” my fingers to sweep it and to measure it without nudging the tool’s pistons further in.
Like I said....worth a shot!
